TSMC Shares Slip Despite Record Profits and $100B U.S. Investment Plan

In a move reflecting the continued dominance of the semiconductor sector in the global tech landscape, TSMC reported record profits driven by surging demand for AI technologies. Despite these strong results, the company's shares experienced a notable decline as investors engaged in profit-taking following a previous rally. Alongside its financial results, the firm announced a massive additional investment of $100 billion in the United States to bolster its manufacturing capabilities and secure supply chains.

This decline comes as chip stocks face heightened volatility, with traders monitoring profit margin sustainability amid competition from peers like Samsung and SK Hynix. Per market data, TSM shares closed at $419.48 on July 15, 2026, retreating from an intraday high of $428.89. Conversely, the healthcare sector saw positive movement as UnitedHealth shares rallied following earnings that indicated a recovery from prior pressures, closing at $418.52 on the same date (per market data).

Investors should watch for support levels on TSM near the July 15 low of $410.75, as this level may dictate the stock's near-term direction. With no immediate corporate catalysts in the coming days, attention remains on U.S. monetary policy signals, particularly the Fed's Monetary Policy Report scheduled for release on July 10 (per the economic calendar), which could impact risk appetite across the tech sector.
